Phosphoric Acid
Physicochemical properties:
1. Mvura inoonekera isina ruvara,Isina kunhuhwirira
2.Melting point 42℃;kuvira poindi 261℃.
3.Miscible nemvura mune chero ratio
Storge:
1. Chengetedza muimba yekuchengetera inotonhorera, ine mhepo.
2. Chengetedza kure nemoto nekupisa.
3. Iyo pasuru yakavharwa.
4. Inofanira kuchengetwa zvakasiyana kubva nyore (zvinopisa) zvinopisa, alkalis, uye mashizha anoshingaira esimbi, uye kudzivisa kusanganiswa kwakasanganiswa.
5. Nzvimbo yekuchengetera inofanira kunge yakashongedzerwa nezvinhu zvakakodzera kuti ive nekudonha.

Shandisa:
Kushandisa zvekurima: mbishi zvinhu zvephosphate fetiraiza uye kudya kunovaka muviri
Indasitiri kushandiswa: makemikari mbishi zvinhu
1.Chengetedza simbi kubva pakuora
2. Yakasanganiswa ne nitric asidhi semakemikari polishing agent kuti ivandudze kupera kwesimbi
3.Zvinhu zvephosphatide iyo inoshandiswa kugadzira chigadzirwa chekugeza uye mishonga yezvipembenene
4.Kugadzirwa kwe phosphorus ine flameretardant zvinhu.
Zvekuwedzera zvekudya zvinoshandisa: acidic flavour, Yeast Nutri-ents, senge coca-cola.
Kushandiswa kwekurapa: kugadzira mushonga une phos-phorus, senge Na 2 Glycerophosphat
